I started to play a record of Hawaiian music last night and noticed that the record was badly warped in one spot.  It looked like it might have been left in sunlight years ago.  I was thinking of trying heat to flatten the record — something like a clothes iron over a towel.  Do any of you have any experience with trying to flatten a significantly warped record?  What worked best?  Is it possible to flatten the record and not still have a problem with integrity of the grooves or the needle being able to track adequately?
